Basics & Theory

HVAC School: HVAC/R Refrigerant Cycle Basics
HVAC School provides a basic overview of the refrigeration circuit and how it works. It is designed to assist a new technician or HVAC/R apprentice in understanding the fundamentals.

HVAC School: Refrigerant Basics
HVAC School says a refrigerant is anything we use to move heat from one place to another using the compression refrigeration circuit, however, the history of refrigerants and the different kinds is quite diverse and interesting.
Issues & Performance

AHRI: AHRI White Paper On Avoiding Contaminated Refrigerants
Air-Conditioning, Heating, and Refrigeration Institute white paper Reports of R-134a Contaminated with R-40 and Other Refrigerants assists contractors and others in the industry in identifying and avoiding counterfeit refrigerants. Recently, batches of R-134a, R-22, R-404A, and R-410A have been found to be counterfeit, and in some instances badly contaminated with other refrigerants, such as R-40. This increases the risk of explosion. (PDF)

Energy Vanguard: HVAC Secret On Air Conditioner Refrigerant Loophole
Energy Vanguard describes a dirty little secret of the EPA and the HVAC industry. As long as manufacturers ship the units dry, they continue to make and sell air conditioners and heat pumps designed to use R-22.

HVAC School: Refrigerants, Flammable & Toxic
HVAC School describes various types of refrigerants and their characteristics around flammability and toxicity.

NIST: Screening Method Identifies 1,200 Candidate Refrigerants To Combat Global Warming
Researchers at the National Institute of Standards and Technology have developed a new computational method for identifying candidate refrigerant fluids with low global warming potential (GWP) as well as other desirable performance and safety features. The new method was used to identify about 1,200 low-GWP chemicals for further study among some 56,000 that were considered.

Plumbing & HVAC: Confusion Reigns as Refrigerants Phased Out
Plumbing & HVAC says as Canada implements a plan to meet our Global Warming Potential emission reductions, the phase-down of halo fluorocarbons (HFCs) is beginning. This means that several of the most common refrigerants are going to, at least partially, disappear over the next 20 years.

US DOE: Phase Out of Climate-Harming Refrigerants Offers Opportunity for Innovation
US Department of Energy says there is opportunity for innovation now that the global community will avoid rampant growth of HFC refrigerant emissions and phase out their usage over time, replacing them with climate-friendly, energy-efficient alternatives.

HVAC School: Refrigerant Charging For A/C & Heat Pumps
HVAC School provides refrigerant charging basics for air conditioning and heat pump systems.

US DOE: Detection & Repair Of A/C Refrigerant Charge
US Department of Energy report HVAC Fault Detection, Diagnosis, and Repair/Replacement investigates the role that measurement uncertainty can have on refrigerant charge verification. There is a large missed opportunity in underperforming residential air conditioning systems and trained home performance contractors may have skills to diagnose and, in some cases, correct major defects.
